SPECIFICATION forming part of Letters Patent No. 672,365, dated April16, 1901.

' Application filed November 12, 1900. Serial No. 36,236. (No model.)

To all whom t may concern.-

Be it known that I, CHARLES HERRON,a citizen of the United States,residing at Chattanooga, Tennessee, have invented certain new and usefulImprovements in Brake-Shoes, of which the following is a specication.

My invention relates to brake-shoes of that class designed to be used onrailway-locomotive driving-Wheels. These shoes are ordinarily made ofcast-iron and are provided with lugs or projections cast integral withthe shoe for the purpose of holding them to the brake-head. Thedifficulty experienced in connection with such shoes is that before theshoe is worn out the holding-lug is liable to break, leaving the shoeinsecurely connected with the brake-head. As a result of this there isnot only loss in the shoes, but danger of derailment due to the shoesdropping upon the rail. Various expedients have been resorted to toremedy this difficulty, but they have been more or less deficient.

To provide a shoe which will be eectual for the purpose and at the sametime at less expense, I have devised a form of lug and adapted it to theshoe so that it may be made separately out of metal tougher and lessliable to break than the cast-iron and have adapted it to the shoe sothat it may be fixed therein in the process of casting, hold the shoe tothe brake-head securely, and permit the full wear of the metal.

My invention is illustrated in the accompanying drawings, in whichlFigure l is a perspective view, and Fig. 2

is a sectional view.

In the drawings, A represents the shoe, of ordinary shape and form, madeof cast-iron.

E represents a lug the outer face of which is curved and which isprovided with a hooked part 5 and a spur 2, upon which the metal of theshoe is to be cast. This spur is formed with any suitable recesses 3,into which the metal locks in the casting to hold the lug securely inplace. Upon the upper or outer part of the lug is formed a shoulder 4,adapted to bear against the rear face of the shoe and to brace itsecurely in place. As will be seen by reference to Fig. l, the lug isnarrower than the shoe, leaving solid metal to each side as well asabove and below, so that it is embedded and securely held in place andfirmly braced. The lug may be made of steel or wrought-iron, forged,swaged, or Inalleable.

I claim as my invention- A cast-iron shoe having an inwardly-curved lugprovided with an offset shank or spur einbedded in the metal of theshoe, and a shoulder extending outwardly to the end face of the shoe andbearing against the rear face, substantially as described.

in presence of two witnesses.
